The ability of pressure gauge with diaphragm to read the different pressure is based on:
- The area of membrane.
- Thick membrane.
- Type of membrane material.
The advantages of pressure gauge with diaphragm as follow:
- Very sensitive due to changes in pressure
- Can be used to measure the height of liquid surface
- Can be used for different pressure
- Can be used at transmitter
- Can be used to measure flow
